Bug 14428: Remove C4::Input

Bug 14428: Remove C4::Input

Jonathan Druart agreed that C4::Input is vestigial code that should be removed.
Here is how I checked. First I found where C4::Input was used. Then, I checked
what functions are in the package: just checkdigit. Then, I confirmed that
checkdigit is not used at all in any acquisition, administration, or member
related perl scripts. Lastly, I took a look at our supposed test file for the
package. It was painfully sparse.

As such, this patch removes the test file and the package file, and removes
C4::Input references from these six files:
- acqui/addorderiso2709.pl
- acqui/basketgroup.pl
- acqui/neworderempty.pl
- acqui/uncertainprice.pl
- admin/aqplan.pl
- members/memberentry.pl
NOTE: neworderempty had 3 lines of it?! Didn't anyone see that?!

Here is the output of what I did to confirm this correction:

mtompset@debian:~/kohaclone$ git reset --hard origin/master

mtompset@debian:~/kohaclone$ grep sub C4/Input.pm
sub checkdigit ($;$) {
                my $temp2 = substr($infl,$i,1);
        if ($rem eq substr($infl,8,1)) {
} # sub checkdigit
mtompset@debian:~/kohaclone$ grep checkdigit `find acqui -type f`
mtompset@debian:~/kohaclone$ grep checkdigit `find admin -type f`
mtompset@debian:~/kohaclone$ grep checkdigit `find members -type f`
mtompset@debian:~/kohaclone$ cat t/Input.t

use strict;
use warnings;

use Test::More tests => 1;

BEGIN {
        use_ok('C4::Input');
}

Apply this patch, and the output of git grep C4::Input will be empty.
Run koha qa test tools (kind of overkill)
